Application ledilanuary 20, 1913. Serial No. 743,154,

. wringer and bucket, wherein the mop is con-Vv lined between rollers normally dispo-sed apart from cach other to permit free insertion of the mop into the'bucket, one of said rollers being capable of being moved toward the other under pressure to press the mop between them in withdrawing the same.

To preventA the mo-p from spreading beyond the ends of the rollersguides are provided adjacent their ends.

This invention is primarily directed to the mounting of the rollers and the construction and operation of the guards.

An object of my invention is to provide a mop-wringcr with a pair of pivotally mounted guards, adapted to support and journal a pair of horizontally disposed parallel rollers at one end with the opposite end of each engaged with the axlev of amovable roller journaled upon an operating lever. The 'axle of the movable roller projects through longitudinal slot in each of the guards to accommodate for its are of movement toward the stationary rollers and thereby enable the guards to be mounted between the respective ends of the movable roller and limbs of the operating lever to offer rigidity to the guards during a mopwringing operation. The pivotal mounting of the guards enables the axle of the movable roller to be journaled in permanently located bearings in the operating lever.

Further objects of my invention relate to oscillating guards disposed adjacently to the wringer rollers with the free ends engaged with the axle of the movable roller of the series, the axles projected through a longitudinal slot in each of the guards. Such guards enable the movable roller to be engaged therewith and be mounted in permanent bearings in the operating lever therefor and offer no resistance to the operation ol" the parts. I l

l The features of my invention are' also directed to the specific form` of construction of bucket vmop-wringer illustrated in the drawings and which 1s more fully set forth.

in the description thereof herein, forming a part of this specication, in which i Figure l is a mutilated side elevationof my improved bucket mop-wringer, showing the upper portion of the bucket and wringer elements in section. Fig. 2 is a front elevation thereof, with the upper portion `oi? the bucket cut away to more clearly illustrate the wringer elements depending within the bucket. Fig. 3 is a detailed sectional View oit' a modified form of wringer, in which only two rollers are comprised instead of three, as illustrated in Fig. l. l

l represents the bucket, having the bracket 2 secured at the upper portionof its inner periphery. The bracket is preferably formed of a strip of metal bent to substantially U-form, with the major portion thereof conforming to the curvatureof the bucket, and with the limbed extremities 3, providing bearings for the pivot rod 4. The rod 4, in .one instance, forms the axis for the guards 5 when the wringer is of the three roller type, and the axle of the roller 4a in a two-roller type. Two guards 5 are provided, one mounted adjacent each limb 3 of the'bracket and preferably adjacent the in-l terior surface thereof, with the roller orrollers intermediate of the guards. In the three roller type of wringer, each guard comprises a metal plate having the oppositely disposed right angled ear extensions 6 and 7 serving as bearings for journaling the stationary rollers 8 and 9 arranged in superposed parallel planes; The ear extensions 6 and are omitted in the two roller type as shown in Fig. 3, the roller 4 being mounted on the rod 4 which forms the axis for the guards. The guards are also each provided with a longitudinal slot 10 in a plane with the pivot rod 4, through which. the axle 1l of the movable roller l2 projects, providing clearance for the roller movement toward and from its companion rollers 8 and 9.

The'movable roller 12 is mounted between the pair of limbs of an operating lever of l'peculiar construction, which lever is pivotally mounted upon the exterior of the bucket and operated by the foot of the operator. The lever comprises a bowed or semi-circular portion 13 extending around one-half of the exterior' of the bucket and the oppositely disposed vertical limbs 14, 15, secured respectively to the ends of the bowed projecting boss faces of the bracket ears.

flexing torsion of the I the operating portion" 13 and substantially at right angles `vertical limband bowed portion 13 of the lever for reinforcement.

, 1S represents op ositely disposed pivot plates secured to the exterior of the bucket, each having a rojecting boss terminating in a pintle 19, adapted to engage through an orifice, in each of the limbs 14, 15, respectively, yof the operating lever. Each plate has a spring 20 engaged therewith and with a limb of of the plate, for urging the lever and its roller to normal position. The use of two springs, one upon each side of the lever equalizes the` force,\insuring freer operation of the lever.

21 represents a tread radiating intermedi-4 ately` from the bowed portion 13 of' the operating lever, adapted to be engaged by the; footof the o erator to depress said lever. 22 represen s a stationary tread secured to the bucket, .whereby thel bucket can be held in position on the. floor to prevent it from tilting during a wringing operation` It will be noticed that the forward ends` of the guards engage with the axle of the movable roller 12, .through the longitudinal slots, and are disposed between the ends of the roller and lever limbs respectively, while the rearward ends are adjacent'the inner This provides a secure connection for the guards, maintains the saine adjacent the ends ofthev rollers during a mop-pressing or wringino operation, serving to prevent the-stran s of Athe mop from becoming entangled with the roller axles and materially resists outward guards.'

The pivotal mountin of the guards offers free movement of felge operating lever through the longitudinal slots, making it possible to provide permanent bearings in lever for theaxle of the movable ioller, connecting the parts against displacement.

the lever, its coil encircling the Iny practice the mop is dropped into the bucket, between the guards and rollers in Open position, thebell crank lever is operated, the single roller moves toward the fixed bearing rollers, the free ends of the guards rocking upwardly to permit of this' movement and to guide the roller toward the -rollers 8 and 9 iniaXial plane with the rod 4, at the same time this rocking of the guards relative to the bearingfbracket, tilts the pair of rollers at anI angle to the vertical plane, causing the rollers to maintain their relative planes when the mop is withdrawn between them.. without injuring the vmop and is a simple, easy operation. There are no-bind'ings b e cause the only guide slots are in the guards which rock freely to accommodate for the arc of travel of the third roller' as it is carried by the bell crank.

This effectively squeezes Having described my invention, I claim:

A mop-wringer comprising a bearing bracket secured to the inner bucket periphery upon one side thereof, a pair of rollen. `supporting slotted guide arms, pivotally secured to s ai'd bracket at their inner ends, their outer free ends extending across the mouth of the bucket, a pair of rollers having bearings in the hinged portionof said arms above and below said guide slots, a yoke-form bell crank lever fulcrumed exteriorly on the lowerportion of the bucket, one end being formed with a foot-piece at one side of the bucket, the other end ext-ending over the top of the bucket and being bent downwardly into the mouth of the bucket on opposite sides thereof, and a third roller having its Aaxle extended through said guard slots and having bearings in said bell crank lever u per ends, whereby the roller slides in said) pair of rollers, the free ends of said guards rocking to angularly adjust the fixed rollers and guide the third roller asitq moves toand from the wringing position In testimony whereof, I have hereunto set my hand.
